未消除的回波(后)
那么,我应该在哪里添加其余的代码呢?我有一个javascript函数和一个css代码。我应该将它们添加到同一个php文件中吗?如果是,在哪里?在html代码之后?在html代码中
这是java脚本代码:
(function(d) {
// user defines
var
swapHours = 0,
swapMinutes = 0,
swapSeconds = 5,
swapTotal = (swapHours * 60 + swapMinutes) * 60 + swapSeconds,
loopSlideShow = true;
// some handy helper functions
function classExists(e, className) {
return RegExp('(\\s|^)' + className + '(\\s|$)').test(e.className);
}
function classAdd(e, className) {
if (classExists(e, className) return false;
e.className += (e.className ? ' ' : '') + className;
return true;
}
function classRemove(e, className) {
if (!classExists(e, className)) return false;
e.className = e.className.replace(
new RegExp('(\\s|^)' + n + '(\\s|$)'), ' '
) . replace(/^\s+|\s+$/g,'');
return true;
}
function textReplace(e, newtext) {
if (d.innerText) e.innerText = newText;
else e.textContent = newText;
}
function nodeFirst(e) {
e = e.firstChild;
while (e && e.nodeType != 1) e = e.nextSibling;
return e;
}
function nodeLast(e) {
e = e.lastChild;
while (e && e.nodeType != 1) e = e.prevSibling;
return e;
}
function nodeNext(e) {
while (e) if ((e = e.nextSibling).nodeType == 1) return e;
return null;
}
function nodePrev(e) {
while (e) if ((e = e.prevSibling).nodeType == 1) return e;
return null;
}
// slideShow setup
var
slideShow = d.getElementById('slideShow'),
slideCounter = d.getElementById('slideCounter'),
firstSlide = nodeFirst(slideShow),
lastSlide = nodeLast(slideShow),
currentSlide = firstSlide,
swapCounter;
classAdd(slideShow, 'ss_scripted');
classAdd(currentSlide, 'ss_show');
// slideShow functions
function showCounter() {
textReplace(slideCounter,
Math.floor(swapCounter / 3600) + ':' +
(Math.floor(swapCounter / 60) % 60) + ':' +
swapCounter % 60
);
}
function resetCounter() {
swapCounter = swapTotal;
showCounter();
}
function makeSlide(newSlide) {
classRemove(currentSlide, 'ss_show);
currentSlide = newSlide;
classAdd(currentSlide, 'ss_show');
}
function nextSlide() {
resetCounter();
var newSlide = nodeNext(currentSlide);
if (newSlide) makeSlide(newSlide);
else if (loopSlideShow) makeSlide(firstSlide);
}
function prevSlide() {
resetCounter();
var newSlide = nodePrev(currentSlide);
if (newSlide) makeSlide(newSlide);
else if (loopSlideShow) makeSlide(lastSlide);
}
function slideUpdate() {
if (swapCounter--) showCounter(); else nextSlide();
}
function startSlideShow() {
resetCounter();
setInterval(slideUpdate, 1000);
}
// wait for onload to actually start the countdown
if (window.eventListener) w.addEventListener('load', startSlideShow, false);
else w.addEventListener('onload', startSlideShow);
})(document);
这是css代码:
.ss_scripted img { display:none; }
.ss_scripted .ss_show { display:block; }
问题是您缺少一个“)” 试一试
while($imgPath=readdir($handle))!==false)如果(
in_数组(
strtolower(路径信息($imgPath,路径信息扩展)),
$允许的类型
))回声'
';
closedir($handle);
))echo'
第一个来自数组()
第二个来自if()
希望这有帮助!:D看起来您忘记用括号关闭if语句了 试试这个
)) echo '
可读性很差,并且应该有句点的地方有逗号,并且缺少一个括号:
while (($imgPath = readdir($handle)) !== false) {
$needle = strtolower(pathinfo($imgPath, PATHINFO_EXTENSION));
// YOU WERE MISSING A CLOSING ( ON YOUR IF
if (in_array($needle, $allowed_types)) {
// THESE PERIODS WERE COMMAS
echo '<img src="' . $imageDir . '/' . $imagePath . '" alt="slide" />';
}
}
closedir($handle);
while(($imgPath=readdir($handle))!==false){
$needle=strtolower(路径信息($imgPath,路径信息扩展));
//你错过了一个结束(关于你的IF)
if(在_数组中($needle,$allowed_类型)){
//这些时期是逗号
回声';
}
}
closedir($handle);
注意,在本例中,我还将使用printf
,而不是echo:
printf(“”,$imgDir,$imgPath);
您缺少的一个“')在回显之前,您可以将javascript代码放在下面的底部:
<script type="text/javascript" src="slideShow.js"></script>
您忘记了while循环和if语句的大括号 也许这就是你想要的:
while (($imgPath = readdir($handle)) !== false){
if (in_array(strtolower(pathinfo($imgPath, PATHINFO_EXTENSION)),$allowed_types)){
echo '<img src="', $imageDir, '/', $imagePath, '" alt="slide" />';
}
}
while(($imgPath=readdir($handle))!==false){
if(在数组中(strtolower(路径信息($imgPath,路径信息扩展)),$allowed\u类型)){
回声';
}
}
<script type="text/javascript" src="slideShow.js"></script>
while (($imgPath = readdir($handle)) !== false){
if (in_array(strtolower(pathinfo($imgPath, PATHINFO_EXTENSION)),$allowed_types)){
echo '<img src="', $imageDir, '/', $imagePath, '" alt="slide" />';
}
}
